This technology takes away the need for any form of construction.

Our systems are prefabricated and installation takes as few as three hours.

With our system, you do not need to own a cow. The systems runs on all biodegradable materials such as any animal dung, vegetable/kitchen waste, food waste, garden weeds, market waste.

A 20 Kgs bucket of any waste will produce all the cooking fuel necessary for the typical 6 – 8 member homestead.

This is made possible by the high level of efficiency associated with the technology where you only require 1/5th the feed-stock for the same daily gas production as conventional technologies.

No Construction

Flexi Biogas systems are prefabricated and install in a few hours.

Rich Organic Fertilizer

The overflowing bio-slurry from the system is a highly nutritious fertilizer ready for absorption by plants without ”burning the plants”. It can also be applied as top dressing or sprayed on plants as an effective pest repellent.

Anything Goes

Flexi systems run on any bio-degradable matter. High calorific feedstock produces  larger volumes of gas.

Efficiency Unmatched

FlexiTech employs “True Cross-flow” fermentation, which means that what goes in one end is fully processed before exiting the other. This also means that 100% of the biogas is captured making FlexiTech the GREENEST biogas plant design yet.

Quick Startup

After installation, the system will have usable volumes of gas within 3 – 5 days, and is normally in full production within 7 – 14 days.
